Network Design: How to Plan an IT Network
What are the steps to follow when designing an effective computer network? Here's a practical guide with useful tips for your business.
In this article
Designing a computer network is not just about hardware and configuring routers, switches and other network devices — it also means defining the client and server systems that make up the network. In this article we'll walk through the main steps for designing an effective computer network, with particular attention to designing the client and server systems.
Identifying user needs
The first step in designing a computer network is identifying user needs and the activities that will run on the network. This helps define the technical specifications of the network and of the client and server systems that make it up. For example, if the network will mainly be used for data processing, you'll need a server with large storage capacity.
Defining the network architecture
Once user needs are identified, it's important to define the network architecture you intend to adopt. The architecture must be able to handle user activities and the resources required by the client and server systems. For example, a client-server network requires a central server that manages data processing and a set of client devices that access the data over the network.
Choosing the network hardware
Based on the technical specifications defined, you can then choose the most suitable network hardware: this includes routers, switches, wireless access points and other hardware components needed to ensure a reliable, secure connection.
It's important to choose quality, branded hardware to avoid compatibility issues and protect the longevity of your investment.
Defining the client and server systems
Designing the client and server systems depends on user needs and the network architecture defined. For example, one server might be dedicated to managing storage and printing resources, while another might handle network security. It's also important to define the technical specifications of the client systems, such as storage capacity and processing power, to ensure a good user experience.
Configuring the network and the client and server systems
Once the network hardware is chosen and the client and server systems are defined, you need to configure the network and the systems to make them operational.
This requires advanced technical knowledge, since the configuration must be carried out correctly to ensure network security and the stability of the client and server systems.
Testing the network and the client and server systems
Finally, the network and the client and server systems need to be tested to make sure they work correctly: this means testing connection speed, system stability and network security.
At this stage, it's important to run a thorough set of tests to identify any issues and resolve them promptly; it's also important to set up a preventive maintenance plan for the network and the client and server systems to keep them in good condition at all times.
The leading vendors for building an IT infrastructure
There are many hardware and software vendors that can be used to build an IT infrastructure. Here are some of the most important:
Cisco: a company specialising in routers, switches and other network devices.
HP Enterprise: a company specialising in servers, storage and networking devices.
Dell: a company specialising in servers, storage and network devices.
IBM: a company specialising in servers, storage and network devices.
Microsoft: a company specialising in server software, applications and operating systems.
VMware: a company specialising in virtualisation software.
Citrix: a company specialising in software for managing virtual applications and desktops.
Symantec: a company specialising in cybersecurity software.
Fortinet: a company specialising in firewalls and network security devices.
Juniper Networks: a company specialising in routers, switches and network security devices.
Beyond these vendors, there are many other companies that produce hardware and software for IT infrastructure: our advice is to evaluate and choose the right vendor based on your company's specific needs and the characteristics of the infrastructure you want to build.

Frequently asked questions
What are the main steps in designing a computer network?
Identify user needs, define the network architecture, select the hardware, set up client and server systems, configure everything, and finally test the network and systems thoroughly before going live.
How do you identify the right network hardware?
Based on the technical specifications defined during the design phase, choosing branded, quality routers, switches and access points to avoid compatibility issues and protect the long-term value of your investment.
Why is it important to test the network after configuration?
Because it lets you verify connection speed, system stability and network security, catching and fixing potential problems before they become critical issues that disrupt the business.
Who are the leading IT infrastructure manufacturers?
Among the most important are Cisco, HPE, Dell, IBM, Microsoft, VMware, Citrix, Fortinet and Juniper Networks, each specializing in a different part of the network infrastructure stack.
